Product Overview
YDS8924EM is a professional high integration device which includes encoding, multiplexing, and modulation in one body. It supports 24 HDMI input, one DVB-C/T/ISDB-T (ATSC optional) tuner input and up to 512 IP input for re-mux. After multiplexing, it output 16 non-adjacent ISDB-T /DVB-T/ATSC carries. It also supports 16 MPTS as mirror of 16 carriers through Data2 (GE) port. This full functionality makes it ideal for small CATV head end system, and it’s a smart choice for hotel TV system, entertainment system in sports bar, hospital, apartment etc
